          The unit of analysis is the directed country dyad year. 
          Baseline controls: relative territorial size of state A vs. state B; logged absolute size of country B; 
          Share of aggregate group governing in state A located in state B;
          Share of aggregate group governing in state A located in own country;
          Dummies for peace and calendar years.  
          Extended controls: logged aggregate group size of governing segments in A and B;
          ethnic fractionalization of countries A and B;
          conflict history (number of past years with ongoing MIDs involving A and B);
          time since last border change involving country A or B (FE).
